Spirit Intercourse: Its Theory and Practice
by J. Hewat McKenzie
1917

To some readers much of the matter will be startlingly new, and the facts difficult to believe. To others, who will accept the phenomena without question, because of previous experience, the theories adduced therefrom may not be wholly acceptable. The facts so far transcend ordinary experience that some cannot do otherwise than reject them, until fuller knowledge prevails upon the whole subject. When first brought into contact with students of this science the writer himself treated the statements made by them as unworthy of belief, and he quite understands the natural scepticism of the man or woman who is at present entirely ignorant of the subject.
